Tsanfau is the furthest planet from the sun in the Tendor System, with an average temperature of below -200 degrees celcius. The planet also hosts a fairly visible ring system of mostly ice and small rocks, where a good portion of the planet's moons are located. Tsanfau's high axial tilt is likely a result of a large collision in the past that offset it from its plane of orbit by a large amount, which also led to some of the planet's moons being offset from its plane of rotation.

The planet is classified as an ice giant, being comprised by various ices alongside gases, while its core is likely made out of metals and rock not unlike terrestrial planets.
